Thank you ! .
I'd wondered as there was NO RIDGE in the cylinders and they and the crank journals looked suspiciously clean & fresh as did the sump & etc. .
I used some electronic calipers as I don't have and Micrometers that big .
I need to remove the damper then the main bearing caps and check the mains too .
This engine was removed running from a '66 C/30 truck for a V-8 Hot Rod project that was abandoned as soon as it was drivable , the old owner then abandoned the engine in his buddy's AC shop where it sat for years before I found it .
I just want to freshen it up with a light overhaul , new pistons , " gapless " piston rings , re size and balance the rods , replace all the bearings and prolly a new cam , tappets & gears too ,for my daily driver '69 Chevy Shop Truck .
How do I remove the wrist pins ? they have no clips nor pinch bolts .
THANK YOU for your rapid response , any more comments / questions ? .
